I use Ctrl+k for exiting Insert mode. So, I did the key mapping on IntelliJ. enter image description here
it seems work well. But, something is wrong.
When I type Ctrl+k, it looks exited insert mode. but after the input ctrl+k, next input is not recognize.
it's difficult to explain for my poor English. so please try setting Ctrl+k as a Exit Insert Mode, and check the behavior.
thank you for your help.
